Coupling for the detachable connecting of two coaxial pipes and carrying column for a room divider containing the coupling

摘要

A first coupling part (6) consists of a bushing (10), a coupling bolt (11) and a ring (12) and is inserted into the end of a pipe (2). Two rest lugs (16) of the bushing (10) engage there into rectangular break-throughs (5) of the pipe (2). The coupling bolt (11) is turnable in the bushing (10) and lies with a head (26) against it. It is joined secure against with the ring (12). This has support shoulders (32) for the support of the face surfaces (4) of the pipes (2, 3). On its circumference it has two wrench surfaces (34). A second coupling part (7) is cup-shaped and is likewise snapped in place with rest lugs (42) in break-throughs (5) of the other pipe (3). The base (43) has an oblong hole (46) through which a bolt (45) of the coupling bolt (11) can be inserted. After turning of the bolt (11) through 90 DEG a spherical supporting surface (47) of the bolt (45) lies against the cylindrical support surface (44) of the second coupling part (7) and clamps the coupling. Through this construction the coupling can be rapidly mounted and it does not project beyond the circumference of the pipes. The coupling is suited especially for connecting elements arranged one over another of a support column of a space divider.
